Minerals in sedimentary rocks emit characteristic visible luminescence called cathodoluminescence (CL) when bombarded by high energy electrons. CL emissions can be displayed as colour images in a cathodoluminescence microscope or as high-resolution monochromatic images in a scanning electron microscope. This provides information not available by other techniques on the provenance of the mineral grains in sedimentary rocks, and insights into diagenetic changes. The book begins with an easily understood presentation of the fundamental principles of CL imaging. This is followed by a description and discussion of the instruments used in CL imaging, and a detailed account of its applications to the study of sedimentary rocks. This is the first comprehensive, easily understood description of the applications of cathodoluminescence imaging to the study of sedimentary rocks.
It will be an important resource for academic researchers, industry professionals and advanced graduate students in sedimentary geology. 'Earth Science: An Illustrated Guide to Science' is one of eight volumes of 'Facts On File's' new 'Science Visual Resources' set. Containing six sections, a comprehensive glossary, a Web site guide, and an index, Biology is an ideal learning tool for students and teachers of science. Full-colour diagrams, graphs, charts, and maps on every page illustrate the essential elements of the subject, while parallel text provides key definitions and step-by-step explanations. The six sections include: 'Planet Earth' - considers Earth's place in the Solar System and its relationship to the Sun, the Moon, and the environment of interplanetary space. Topics covered in this section include solar and lunar eclipses, tides, seasons, and Earth's magnetic field. 'Earth's History' - examines the basic principles used by geologists to determine the age of rocks and the use of fossil evidence in determining the sequence of geological events.
There is a comprehensive survey of the history of life on Earth and a general description of each of the geological eons. A sequence of pages traces the history of the North American continent through each geological period, showing the prevailing conditions and the kind of life forms that have flourished there. 'Earth's Rocks' - is concerned with the processes that create and modify Earth's geology. The relative abundance of minerals on our planet; the formation of igneous, sedimentary, and metamorphic rocks; and the processes of plate tectonics are examined in this section. 'Air and Oceans' - is an overview of the shallow but complex layer of gas and water that surrounds our planet and supports all animal and plant life.
The types and causes of all significant weather phenomena are covered here, as well as the intimate connections between the oceans and the atmosphere. Heat transfer between air and oceans and the planet-wide systems of circulation driven by solar energy are also explained here.
'Erosion and Weathering' - looks at the constant wearing down of the Earth's rocks by the combined actions of the atmosphere and the oceans. Mechanical and chemical weathering, the formation and movement of soil, and the geological forms produced by the actions of rivers and glaciers are all featured in this section. Wind erosion and the formation and spread of desert landscapes are also covered. 'Comparisons' - gives the relative scales of major planetary features, such as oceans, rivers, continents, and mountain ranges. From Library JournalScience author Allaby (Illustrated Dictionary of Science; A Dictionary of Earth Sciences) has compiled more of a dictionary than an encyclopedia, covering roughly 3000 alphabetically arranged terms pertaining to climatology and meteorology, as well as geology, biology, and astronomy.
The longest entries (mostly biographical) run nearly two pages, but the majority are brief definitions. Allaby succinctly describes noteworthy named storms and also includes local weather terms, from the Indian andhis to the Argentinean zonda. Unfortunately, he omits some terms of particular interest to American and Canadian users, including Alberta clipper, humidex, first heave, Mount Washington Observatory, and storm chaser. The entries are extensively cross-referenced and sometimes include a reference or two to web sites or books. Quite a few of the print references, and a full quarter of the titles in the 'Bibliography and Further Reading,' are to other works by the author. Five appendixes complete the work: a 'Chronology of Disasters' (selection criteria unspecified), a 'Chronology of Discoveries,' a chart of the geological time scale, a list of destructive 'Tornadoes of the Past,' and a list of web sites. Given the brevity of the entries, this is an optional purchase for libraries with large scientific and technical reference collections.
Smaller academic and public libraries might find it useful but should also consider the less expensive The Facts On File Weather and Climate Handbook, also compiled by Allaby, or even a dictionary, such as Storm Dunlop's A Dictionary of Weather or The Facts On File Dictionary of Weather and Climate.Nancy R. Curtis, Univ.
Of Maine Lib., Orono. This book on Applied Clay Mineralogy is comprehensive. It covers the structure, composition, and physical and chemical properties of kaolinite, halloysite, ball clays; bentonites including sodium montmorillonite, calcium montmorillonite, and hectorite; and palygorskite and sepiolite.
There is also a short chapter on common clays which are used for making structural clay products and lightweight aggregate. The location and geology of the major clay deposits that are marketed worldwide and regionally include kaolins from the United States, Southwest England, Brazil, and the Czech Republic along with halloysite from New Zealand and ball clays from the US, England, Germany, and Ukraine. Bentonites from the U.S. And Europe are included along with palygorskite and sepiolite from the U.S., China, Senegal, and Spain.
The mining and processing of the various clays are described. Extensive discussions of the many applications of the clays are included. The appendices cover the important laboratory tests that are used to identify and evaluate the various types of clay. Many figures are included covering electron micrographs, processing flow sheets, stratigraphy, and location maps. Provides the structure and composition of clay minerals, as well as their phyisical and chemical properties.
Placas Tectonicas En El Mundo
Discusses pplications for Kaolin, Bentonite, Palygorskite and Sepiolite. Contains appendixes of laboratory tests and procedures, as well as a test for common clays. This is the first book to cover Holocene geology and geomorphology of the entire 8,500 kilometers of the Brazilian coast.
It is aimed at third and fourth year undergraduates, post-graduate students, scientists and managers. It characterizes the coast in terms of holocene geology, geomorphology, oceanographic conditions and the location of the barrier types. Separate chapters outline the types of barrier in each state, beginning in the south and proceeding to the north. Special emphasis is placed on the stretches of coast where the detailed morphology and stratigraphy of barriers has been previously determined. This is the first attempt to summarise the geology of Africa by presenting it in an atlas and to synthesise the stratigraphy, tectonics, economic geology, geohazards and geosites of each country and territory of the continent.
Furthermore, the digitised geological maps are correlated and harmonised according to the current stratigraphic time table. The atlas aims to contribute to capacity building in African Earth Sciences and to initiate research and economic opportunities by providing a database of basic geological background information. The favourable reception given to the first (1996) edition of this book suggests that the joint treatment of electron microprobe analysis (EMPA) and scanning electron microscopy (SEM) with a specifically geological slant has been found to serve a useful purpose.
It was therefore decided to proceed with this second, revised and updated, edition. The inclusion of both EMPA and SEM can be justified on the grounds that the instruments share much in common and their functions overlap: SEMs fitted with X-ray spectrometers are often used in analytical mode, while EMP instruments, though designed primarily for analysis, also have imaging functions similar to those of the SEM.”. A practical book for geologists involved in petroleum production, here is a comprehensive review of basic techniques in production geology, the links with related subjects, and the function of geologists in the planning and operation of all phases of oilfield development. The first part discusses the basic techniques used in the analysis and graphic representation of the stratigraphy, tectonic structure, reservoir sedimentology and hydrocarbon distribution of an oilfield. The second part describes how this knowledge is applied in the various phases of field development. The mutual support between production geology and neighbouring disciplines such as seismology, log interpretation, reservoir engineering is stressed. Throughout the book, the text is secondary to the illustrations; these are examples, mostly hypothetical, of conditions and techniques discussed, designed so as to bring out as clearly as possible the importance of the points.
Earth as an Evolving Planetary System presents the key topics and questions relating to the evolution of the Earth's crust and mantle over the last four billion years. It examines the role of plate tectonics in the geological past via geological evidence and proposed plate reconstruction.Kent Condie synthesizes data from the fields of oceanography, geophysics, planetology, and geochemistry to examine the key topics and questions relating to the evolution of the Earth's crust and mantle. This volume provides a substantial update to Condie's established text, Plate Tectonics and Crustal Evolution, 4E. It emphasizes the interactive nature of various components of the Earth system on time scales of tens to hundreds of millions of years, and how these interactions have affected the history of the atmosphere, oceans, and biosphere.
New insight on interaction and evolution of Earth system. Examines the role of castrophic events in Earth's history. New section on the evolution of the mantle.
Earth belongs to a group of small, inner solar-system planets, including Mercury, Venus, and Mars, which all consist of a mantle made of silica-based minerals above an iron-rich core and crusts that show evidence of meteorite bombardment and volcanic lava flow. Beyond these basic similarities, and despite their similar formation processes in the inner solar system, these four planets are strangely different from one another.While the Earth's surface temperatures are relatively constant, Mercury goes through daily cycles of heat high enough to melt lead and cold deep enough to freeze carbon dioxide gas. Though the study of geology started with the Earth, making it the standard against which other planets are compared, 'The Earth and the Moon' compares the Earth equally with other planets to clearly display the similarities and differences between the various orbiting bodies. This volume discusses the fundamental aspects of the Earth as a planet, including its size, mass, orbit, surface appearance, atmosphere, and the causes of its seasons. This volume also covers the evolution of the moon in relation to the geological features of the Earth and the history behind the successful space missions to the moon. Perfect for those interested in understanding the science and history behind the exploration of the Earth and Moon, this volume presents an unbiased view of this exciting topic.
Here is a book for everyone who has an interest in how our planet works, what has happened during its 4,550 million year history and what might happen in the future. It tells how Earth scientists study the pattern of events that have shaped the planet and guided the evolution of life on Earth. In clear and simple language it describes how the effects of these events are measured and the careful detective work needed to unravel the extraordinary complexity of Earth history. The latest advances in dating methods, including the detection of regular patterns of global climate change, are explained and illustrated with real case histories.
Our environment is unexpectedly unstable. Dramatic and catastrophic changes in the environment have directed the evolution of life and the rise of Man, and we can expect similar events in the future. If we are to control their effects, we will have to understand what to expect - and what could happen if we try to intervene in the 'natural' development of our home, the Earth.Download.
This fully revised and updated edition introduces the reader to sedimentology and stratigraphic principles, and provides tools for the interpretation of sediments and sedimentary rocks. The processes of formation, transport and deposition of sediment are considered and then applied to develop conceptual models for the full range of sedimentary environments, from deserts to deep seas and reefs to rivers. Different approaches to using stratigraphic principles to date and correlate strata are also considered, in order to provide a comprehensive introduction to all aspects of sedimentology and stratigraphy.
